Weegy: A protostar forms once the nebular cloud condenses and the core begins to heat vandar|Points 911|

User: What are steps of stellar evolution in the correct order.

Weegy: 1. [ A nebula, an immense cloud of hydrogen gas and dust, condenses into smaller regions of matter.
On occasion, one of these regions collapses under the force of its own gravitational attraction, often triggered by an outside force, like a nearby supernova-an explosion of a star.
After the collapse of a cloud, atoms begin gravitating together to form a condensed center. The condensed center is a protostar. As gravity pulls in more gas and dust, pressure builds, causing the protostar core to heat up.
Clouds and matter begin to rotate around the protostar and flatten due to their rotation. They surround the protostar like a rotating disk.
The protostar continues to grow and its core continues to heat. When the core is hot enough, nuclear fusion begins. The start of nuclear fusion is technically the beginning of a star's life.
Eventually, when the nuclear energy runs out, the star dies. Depending on the size and mass of the star, it can go through many stages and die in different ways-one of those ways being a supernova.

User: Observations of the solar system support the nebular theory because _____.

User: Which statement is true?
Inner and outer planet composition supports the nebular theory because heavier elements condense close to the Sun, and lighter elements condense at cooler temperatures.
The big bang is a theory about the origin of the solar system.
Nuclear fusion occurs at cooler temperatures, away from the Sun.
The inner planets are gas giants, and the outer planets are rocky.

User: Current observations of a new star forming support the nebular theory because they show a disk-shaped plane surrounding the star, which may eventually form

Weegy: The Nebular Hypothesis is the theory that suggests that the interstellar dust within a nebular cloud is the most important component of planet formation. User: The ___ theory suggests that protoplanets began to form around the protosun from many collisions and combinations of gas and matter, called ___ . Weegy: It is the nebular theory.

A red giant white dwarf black dwarf supernova is one way a star might die, and it can trigger the beginning of a new star's life cycle. red giant white dwarf black dwarf supernova Weegy: Stars are sustained by the nuclear fusion reactions taking place in their cores. For stars on the main sequence, such as our own Sun, this mostly involves combing hydrogen to form helium. [ The energy that these reactions produce is enough to support their mass against its own gravity.
As a star runs out of fuel it can expand and will begin to form heavier elements such as carbon and iron (most of the matter in our solar system comes from extra-solar sources). Once it finally exhausts all of its fuel it will begin to collapse. It is here that the stars begin to undergo different fates.
Our own sun will collapse until it ... (More)
